I picked up the teacup and took a sip of the slightly cold tea, and then gently put it down, and Lu Xue silently refilled the tea for me. The courtyard was silent, Sun Hao and they went to worship Sanqing with Qingyan, I heard that a simple blessing ceremony was prepared for them later, everyone wanted to call us together, but Feng Xiaolu saw that I was motionless and seemed to be thinking about things, so he shook his hand in front of my eyes, and saw that I didn't react, so he was very relieved to urge everyone to leave quickly, Lu Xue smiled and shook her head to refuse, and then everyone left the courtyard with Qingyan in Sun Hao's lamentation and Feng Xiaolu and Zhou Ying's ambiguous laughter.

The courtyard was quiet, the clouds in the sky did not know when to cover the sun, the sun shone through the mottled clouds, the wind chimes on the old house made a crisp sound in the breeze, I picked up the teacup and gently let the cooling tea flow into the mouth, fell into the abdomen, the sweetness between the teeth and the residual faint bitterness in the tongue slowly diffused in the mouth, the taste of tea is always unfinished and want to welcome and refuse. Putting down the teacup, Lu Xue continued silently. None of us spoke, just quietly doing our own movements, which seemed so unreal but clearly visible in the dappled sunlight.

Legend has it that Zhuang Zhou once dreamed that he had become a butterfly in his sleep, and when he woke up, he was very suspicious, wondering if he had become a butterfly in a dream, or in a dream that had become a butterfly in Zhuang Zhou? So which one is true? And how do you distinguish the real?

Zhuang Zhou began to doubt the truth of himself and the world around him because of a dream, but he didn't seem to have a clear definition of what reality was, but became suspicious, confused and even nervous.

How do you define what is real? I shook my head slightly, gently picked up the teacup again, and poured the tea into my mouth, but suddenly I was so excited by the hot tea that I hurriedly turned my head and spit it out.

"It's not hot, is it, little brother? I just saw that the tea was out of boiling water, you didn't get it, right? Lu Xue looked at me nervously, wanting to go up and check it out, but stopped a little shyly.

"It's okay, it's me who wants to get into the middle of things." I shook my head and said.

Lu Xue saw that I was okay, so she sat down again, dragged her cheeks with one hand, and slowly poured the teapot for me with the other hand, "I saw that you were so engrossed that I didn't bother you when I just got water, and I called you several times just now." ”

"I'm sorry."

Lu Xue smiled and shook her head, not asking me why I apologized, but from her calm and elegant expression, I could still tell that she knew why I apologized. Somehow I had the illusion that Lu Xue knew all my thoughts, that we didn't need words, no movements, and no eyes to look at each other, as long as I sat quietly next to me, Lu Xue would always read my thoughts. It feels weird, as if we've only known each other for a month, as if we've known each other for a long, long time.

I shook my head violently to dispel the delusional thought. When I turned my head, I saw Lu Xue winking at me playfully, did she understand it again?

"You know what I'm thinking?" I asked calmly.

Lu Xue smiled and nodded, "I'm thinking about Zhuang Zhou Mengdie." ”

I nodded, then shook my head, "I can't prove what is real, or whether the butterfly's dream really exists." ”

"I think, therefore I am." Lu Xue said lightly.

I nodded, "A quote from Descartes, who was once confused by the unreal and the real." ”

"So he used falsification."

I nodded again, "He didn't imagine that other worlds existed, but that he proved whether our world was real, whether we lived in this world were real." ”

So, back to the source, when we doubt the existence of everything, we don't have to doubt our own thoughts, because the only thing we can be sure of is the existence of our own thoughts. We can't deny our own existence, because when we deny it, when we doubt, we already exist. ”

I shook my head, "This can only prove that things are moving, and using the trajectory of things to prove the existence of things is theoretically true, but it still can't explain what is 'real', or whether another 'reality' exists, whether they stand side by side or are dependent." ”

"Brains in a vat?" Lu Xue said with a smile.

I nodded, "Zhuang Zhou Mengdie, Butterfly Dream Zhuang Zhou, how to prove it?" ”

"I think Zhuang Zhou, his old man will know."

"Why?" I asked, frowning.

"Zifei fish." Lu Xue blinked and laughed.

"Zifei fish? Zifei fish, the joy of Anchi fish? ”

"The son is not me, and I know that I don't know the joy of fish?" Lu Xue replied with a smile

"The child is not a fish, and the child is not me." I repeated these two sentences aloud, bowing my head in contemplation, and Lu Xue looked at me with a smile and shook her head slightly.

"Zi Fei Fish, the joy of Anzhi fish? The son is not me, and I am not a fish? I raised my head sharply and frowned at Lu Xue, Lu Xue still looked at me with a smile, nothing changed, it seemed that she knew that I would think so, as if she knew Zi Feiyu's explanation.

"Isn't that weird?"

I nodded again

"When I first heard this story, it was strange that a man who wondered if he was in a butterfly dream would use sophistry to argue with people. I was very suspicious for a while, and then I thought of this answer, although there was no evidence to prove it, but I felt that such an answer should be Zhuang Zhou's answer. ”

I nodded, "That is, he has been pursuing this question since he dreamed of butterflies, and then he seems to have found some evidence, or maybe he found an excuse to convince himself." ”

Luxue smiled at me again, her smile was beautiful, and for a moment I felt as if I was smiling in response to her.

"But given that Zhuang Zhou is one of the main exponents of the Taoist school, it is likely that his proof is 'Dao'. But in terms of evidence, you can't prove yourself with yourself. So this may still be an unsolvable problem. ”

"Then let's go and ask Qingyan Dao Chief." Lu Xue said with a smile.

'Ask him what?'

"Of course, if we ask him what we met on the road, he always has to give an answer, so that he can solve the culprit that caused Brother Xiaoshan to fall into contemplation and what is the 'real'? Is that destiny still a matter of six degrees of separation? ”

"Well, you can try to solve the problem at the source."

True, why do I think about what is real? Do you want the world to be real, or do you want the world to be unreal? I shook my head slightly and laughed self-deprecatingly, maybe I was afraid of self-denial, maybe I was afraid of losing, losing my biggest reliance, my shallow understanding of the world, and I was afraid that I would become nothing and lonely again.

"It doesn't matter if this world is real or not, but I know that the clouds in the sky are drifting, the wind is gently blowing, I can enjoy a moment of laziness and tranquility in this courtyard on such a calm afternoon, and there is also a little mountain brother with me, and that is enough." Lu Xue gently put down the teapot that had refilled the water for me, and said with a smile.

Looking at Lu Xue's smile, I felt a panic for no reason, I hurriedly closed my eyes, took a deep breath to calm my mind, and when I opened my eyes again, I saw that Lu Xue was still smiling at me, and that smile was full of anticipation and encouragement.

The sun showed out of the clouds again, and the golden sunlight poured down on Lu Xue's body, and also on the necklace with a dolphin pendant she was carrying, and the jade dolphin shone brightly in the sun.

Zi Fei Yu I thought to myself.
